I can't change the tag to a columns

Hi, I know this should be a very easy task, but I really can’t find the answer. As you can see in the attached image. I’m trying to change the structural column tag to a specific tag. I’ve seen some examples where using the ChangetypeId method. However, for some reason it doesn’t seem work. I already tried:

tag.ChangeTypeId(tagType.Id)
tag.ChangeTypeId(tagType.GetElementId())

But non of them work. I don’t mind changing the tag after or during the creation of the tags, I just want to create tags for my column with that specific tag. If there are more options that someone can show me I’m open to any options (except using third party packages). Thank you so much

Why not use the method that allows you to specify the tag type?
